I've pasted my entire lilo.conf at the bottom of this msg.

You're probably right. Here are the details of what happened.
My old motherboard was an Abit kt7a-raid. It had an extra ide controller
providing ide channels 2 and 3 into which had plugged in my hard drives (it
supported ATA-100, while ide 0 and 1 only provided ATA-66). My primary disk
showed up as /dev/hde. To get things to boot I had the following two lines
in my LILO configuration:
disk=/dev/hde
bios=0x80
On my new mb the same primary disk is on ide 0 (it shows up as /dev/hda) so I
use no drive id remapping.
Here's what happens when I try to use the windows tools to get it to boot.
1. windows installation -> I still get the LILO prompt on boot
2. fixboot -> I still get the LILO prompt on boot
3. fdisk /mbr -> the computer stops when it's time to boot from the disk.
It's not frozen (I can toggle caps lock and num lock, reboot with
alt+ctrl+del) but it just sits there.
4. fixmbr -> gives me the msg "Missing operating system"
I can boot my original linux installation (I had to change all references
to /dev/hde to /dev/hda).
I've also blanked the entire windows partition in hopes of removing any hidden
reference to the old setup.
Thanks for your help
